If you want to add a shower filter in-line with the ShowerStick so you’ll have both soft and filtered water, the KDF filter is a great option. Effectively removes 95-99% of chlorine and controls the buildup of microorganisms such as bacteria, algae, fungi and mold. In addition, it works more effectively at higher water temperatures than carbon filters which makes it perfect for showers. Not only does it help to protect you from these contaminants but it also protects the ShowerStick’s softening resin to ensure it has a long lifespan. If however, your water doesn’t contain these contaminants or if you already have a whole-house water filtration system then you may not need to add the KDF filter.
Replace the KDF filter yearly (if 2 people are using the shower) or sooner if you smell the presence of chlorine. Filtering chlorine from your shower water benefits you, and it’s also a great way to protect the resin to ensure it performs well and has a long life.
